Well, yes, that's the instructions I followed. I had my wife holding and pulling on the glass while I worked with the regulator. Brian on the mailing list said I have to get the plastic mounting nut out of the window/regulator in order to free it, and the suggested using a socket to collapse the fingers.
I did sort of pick at them but did not apply too much pressure, not knowing what came apart how, and not wanting to increase the cost of the repair by breaking the glass.
I'll have another go at it tomorrow evening.
